A concave mirror form a real image of height 4 cm of an object 1 cm placed 20 cm away from the mirror clculate the image distance what is the focal length of the mirror
Answers
Answer:
Thorlabs has a wide selection of spherical concave mirrors with metallic or dielectric coatings that together span the 250 nm - 20 µm spectral range, with focal lengths from 9.5 mm to 500 mm. Our mirrors with metallic coatings are offered in UV enhanced aluminum (250 - 450 nm), protected aluminum (450 nm - 2 µm), protected silver (450 nm - 2 µm), protected gold (800 nm - 20 µm), and mid-infrared enhanced gold for Herriott cell mirrors (2 - 20 µm). Our mirrors with dielectric coatings offer >99% average reflectivity in the 350 - 400 nm, 400 - 750 nm, 750 - 1100 nm, or 1280 - 1600 nm spectral ranges.
